摘要： A failure detection device is disclosed. The failure detection device may receive operations data related to operations of a set of parts of a machine. The failure detection device may process the operations data using a condition-based processing technique. The condition-based processing technique may be associated with mapping initial values of data elements of the operations data to binary values based on satisfaction of a first set of conditions by the initial values. The failure detection device may detect a presence of a possible issue with the operations of the set of parts based on a second set of conditions, associated with the binary values and the initial values, being satisfied during a time period. The failure detection device may perform, after detecting the presence of the possible issue, a set of actions related to addressing the possible issue.

摘要： Provided is a residual stress estimation method and a residual stress estimation device capable of suppressing the number of cut pieces to be collected for measuring inherent strain without deteriorating residual stress estimation accuracy. In a case where it is assumed that the inherent strain is uniformly distributed in one direction in a structure, a user measures residual stress from a cut piece collected in a region in which the inherent strain is uniformly distributed and inputs the measured value to the residual stress estimation device. The residual stress estimation device estimates a two-dimensional inherent strain distribution on an analysis surface perpendicular to the one direction in the structure using the input residual stress measured value, transfers the estimated two-dimensional inherent strain distribution to the one direction, and estimates a three-dimensional inherent strain distribution in the structure.

摘要： A system and method of non-intrusive thrust measurement of a gas turbine engine. The system comprises a transmitter disposed at a boundary of fluid flow and at least one receiver adapted to receive transmissions from the transmitter. A processor is coupled to the receivers to determine a parameter from a characteristic of the transmission at the receiver suite and adapted to determine a thrust parameter from the parameter. A method for non-intrusively measuring engine thrust includes transmitting a wave across the exhaust plume, receiving the transmitted wave and determining a measurement parameter of the exhaust plume based on a characteristic of the received wave, and comparing the measurement parameter to a reference parameter and determining the thrust based on the comparison.

摘要： Provided is a testing system for a drivetrain, the testing system capable of simulating the slip behavior of a tire. A testing system is provided with: tire speed calculation units; a vehicle speed calculation unit; vehicle driving torque calculation units which calculate vehicle driving torque values; and speed control devices which output command signals such that the deviations between command values and output values from encoders are eliminated, respectively. The tire speed calculation units calculate the tire speed values on the basis of tire driving torque values obtained by subtracting the vehicle driving torque values from output values from shaft torque meters, respectively, and the vehicle speed calculation unit calculates the vehicle speed value on the basis of the vehicle driving torque values.

摘要： A method for determining an energy yield loss of a first wind turbine (1-49) of a wind farm (51) that includes a plurality of wind turbines (1-49). The first wind turbine (1-49) is operated in a reduced energy yield mode that is outside an energy-optimized normal operating mode and a reduced energy yield of the first wind turbine (1-49) is determined. At least one second wind turbine (1-49) is selected according to a pre-determinable criterion. The energy yield of the at least one second wind turbine (1-49) is determined and depending upon the energy yield of the at least one second wind turbine (1-49), an energy yield potential of the first wind turbine (1-49) is determined. The difference between the energy yield potential of the first wind turbine (1-49) and the determined reduced energy yield is formed.
